[net.ham-radio] Computer Controlled Scanners?

john@anasazi.UUCP (John Moore) (07/19/85)

There are many scanners in the world with all sorts of neat features.
Unfortunately, they never seem to do quite what you want. For example,
when searching a frequency range for new signals, there is no way to
skip specific frequencies which you don't want to hear.

I am looking for information on scanners which can be interfaced to
a computer so that the computer can exercise real-time control over
the parameters of the radio - especially frequency. I know of two
scanners with computer control (one made by Bearcat, and the other
a clone of the Regency MX-5000 made by AOR). Unfortunately, it is
pretty difficult to get information on either one. The last time I
talked to Bearcat (a while ago), they were unwilling to part with the
interface specs. Rather, they wanted one to buy a software package for
the computer of interest and just run it. I was unable to determine for
sure if the frequency skipping option is possible, but it looks like it
may not be. The computer may just be capable of loading the frequency
registers and reading usage counts, etc. If anyone knows more about this,
I would like to hear from them.

The AOR scanner is even more mysterious. It appears to be a Regency MX-5000
except with a Japanese name. There is an RS232 adapter for it for around
$130. However, finding out what you can do with that is an interesting
problem. My brother, who lives in Tokyo, is trying to find out but he
is not likely to succeed. Again, help!!

Does anyone know of any other computer controlled scanners? Regency? JIL?
etc...

Here's a reposting of a past article on a computer controlled
scanner product.   A friend has one, and I saw a demo by the
inventor at our scanner club meeting.  After seeing the demo,
I suggested a few new features, such as a producing a histogram in
the search mode, which are now incorporated into the latest version.

  -----------------

	       Comquest	SXP-210	Scanner	Expansion Package

   There was a demonstration at	the Wheaton  Hamfest  of  a  new  $110
   software  package  that  allows a Commodore 64 personal computer to
   control a Bearcat 210XL scanner.  The SXP-210 comes	with  software
   on  a  5.25"	 floppy	 diskette and a	special	interface cable, which
   connects the	64 to a	ribbon cable within the	210XL.

   Uniden's hasty withdrawl of the Bearcat CompuScan 2100  leaves  the
   SXP-210  as the only	product	that will allow	a personal computer to
   control a VHF/UHF scanner.

   Some	of the more interesting	features listed	in the	sales  litera-
   ture:

      -	Expands	[stock]	18 channels to 50.

      -	Removes	the software constraints [of  the  stock  210XL]  that
	prevented operation on the 6m and 10m amateur bands.

      -	Color graphics that identify type of radio service being moni-
	tored. (Police,	Fire, Amateur, etc.)

      -	With a	printer	 you  can  generate  a	chronological  log  of
	selected channels as they become active	along with the time of
	day that the transmissions were	received.

      -	Includes 12 hour time of day clock w/AM	and PM designations.

      -	Adds a "count" feature to the 210XL, similar  to  the  one  on
	more expensive scanners.

      -	Edit mode allows flexible control of all channel info.

      -	Includes an improved search mode with  a  "Hold"  [?]  trigger
	feature.

      -	Channel	lockout/selective scan delay.

      -	Includes a special list	function that displays freq  info  for
	all 50 channels	simultaneously on one screen.

   Installation	appears	simple.	 A pliers is used to crimp a  supplied
   socket  onto	an existing ribbon cable within	the 210XL.  An umbili-
   cal cable plugs into	this socket and	into the computer.

   One drawback	of the this 64/BC210XL setup is	the scan rate rate  of
   only	8 channels/sec,	about half the scan rate of a normal 210XL.

	The Conquest SPX-210 looks interesting and is an approach that
might be kludged for other scanners.

	I have read a description of the JIL SX-400 as "computer
controllable", and indeed they sell an interface for an NEC PC. I
called them up and asked for interface specs for the scanner itself
so that I could control it with a different PC. The response was:
"Do you work for the government? If not, we can't give you the
specifications. We have no maintenance manual - the product is
proprietary".

	Sigh...
